Sažetak
Modernization of height reference systems has started in the past decade in the field of basic surveying work in the world. It was triggered mostly by intensive development and daily use of satellite positioning methods, as well as by increased accuracy of global and regional gravity models. The accomplishment of one-centimetre accurate geoid model in higher resolutions and implementation of the World Height System is expected in the next decade. The current height systems in the world, usually defined by means of tide gauge measurements and realized by means of levelling, do not meet the growing and diverse needs of geodetic engineering practice, especially in demanding infrastructure jobs. Therefore, the redefining of Croatian height system and reconstruction of its frame (Croatian Height Reference System 1971) will be an important task in the upcoming years. This paper analyzes the current definition of Croatian height system and its framework, and considers the strategy for its modernization with the aim of finding the best long-term solution within the current world’s experiences and guidelines.
